IMAGHIlll'llil FOR MAKING GROOVED STIIS.

. l Application med .Tune 28, 1924. Serial No. 723,019.

This invention relates to machines for 'making grooved strips, and is fully de shown in thev accompanying drawing in which Figure l'is a partial side elevation machine embodying the invention;

VFig 1a `is a continuation .of the same; Fig. 2 is an enlarged vertical section on the line 2 of Fig. l; i

a Fig. 3 is a partial longitudinal section on the line 3 3 of Fig. 2.

Fig. 3 is a frontelevation of a strip of,

the metal acted upon. F Figf4 is a vertical section on the line 4 of Fig. 5 is a similar view on the line 5 of l. g I S Fig. 6 isa cross section of the metal strip -as it emerges from the forming rolls of Fig; 5.

Fig. 9 is a lbroken elevation of the form'- ingrrolls taken on the line v9 of Fig. la; l ig. 10 is a cross section of the strip as it emergesfrom the forming rollsV of Fig. 9; Fig. 11 is a transverse section on the line 11 of Fig. la;

Flg. 12 is a transverse section` of.A the strip as it emerges from the. forming rolls as l shown in Fig. 11;

Fin'. 13 is a transverse vertical section on the line v13,015 Fig. l;

. Fig. 14 is a section through the strip as it y emerges from the rolls of Fig. 13;

Fig.- 1'5 is a broken elevation of the formmachine having a main-frame which is supported upon suitable le 21, and which has amachined upper sur ace 22fto whicl is bolted. a -casting23 having beveled edges 24 which are held between: longitudinal strips25 which extend throughout the mahine and which are screwed t0 the .frame by Y Fig. 8 isa cross section of the strip asit f emerges from the rolls of' Fig. 7.

'permitting16`gi- Thecasting 23 as shown in Fig. 2l carries boxes 27 in which is journalledl a shaft 28 lwhich carries la worm wheel 29, the latter meshing with a worm 30 onA haft 31 whichdextends throughout the length of the machine and which is driven by any suitable source of power not shown.

' The shaft 28 has keyed thereon a gear 32 whichfmeshes with a gear 33 `on the shaft -y 34, thel latter being journalled in suitable bear1ngsy35 swhich are separated from the bearings 27 by means of springs 36 and pressed down by means of adjusting screws The shafts 28 ing rollers`38 and 39,?the former having an extension 40` which shears out notches B from the strip A (Fig. 3a) as the strip passes through the shearing rolls. These the strip-5A.

vFollowing the first set of'cutting rolls are three sets of feeding'rolls, as shown in Fig. 4, for vupper and lower -rolls 41 and 42,`

and 34 carry rotarysliear- Tnotehes will occur at regular intervals in 4 which are mounted-upon shafts 43 vand 44,

which are 'ournalled in, casting 23 as shown in Fig. 2, t Ne shaft 44 having a woim wheel 45 which is driven by a worm wheel46 on the shaft 31.

Following the three sets of feeding'rolls is the first pair oil?l forming rolls 47 andi/48 A which are' carried by shafts'49 and 59 which are similarly mounted in bearings carried by castings 23', as shown in Fig. 2, the lower shaft 59 carrying the worm wheel 60 which meshes with a worm wheel 61 on the shaft 3 1, the -two shaftsbeingeared -together by means o. gears 61 "van 42 it passes -throu h the first pair of forming rolls 47 and the form A1 of Fig. 6.

Fig. 7 shows a second vset of forming rolls 63 and 64 which deepen thedepression shown 8 emerging therefrom in m 62.- As the fiat .strip A emerges from the feed rolls 41 and in the stri which emergestherefrom in the v i wninFig. 8. y Fig. .9 s howsf another pair rolls 65 and 66 which are similarly mounted of formingand driven,-through which the metal strip passes, em erging' in thejform A", as shown in. Fig. 10. l Fig. 11 shows thenext set of forming rolls, `the lowerroll 67 being mounted on a Ashaft 68 which has@ Worm. Whel 59 Whill is driven b means of a worm 70on 4the shaft 31. e shaft 68 is mounted in a casting 71Y which is held between longitudiil strips 25 in the same way. as the castings ldlers 72 are mounted upon shafts 73 -which are journaled in the casting 71, the faces of the idlers lying near the flanged.f

edves of the roll 67 so as to bend down the sides of the strip At, as'shown in Fig. 12.

A second set of idler rolls 74:, as shown in Fig. 13, loverlie 'roll 7 5, which is mounted on a shaft 76. These idlers and shafts, are

driven inthe same manner asshown and de scribed iny Fig. 13. When the stri A emerges rom'this set of folding rolls it has U20," 7, 'and are similarly mounted in casting-23..- These serve to hatten the strip shown at A,

' .provi 30 the formN shown in Fig. 14.

Fig. 15 shows a set offlattening rolls -77 both of which are driven,as in Figs. 5 and he final operation, YSeverin the finished strips, isaccomplished b the s earing rolls,

shown 1n-Fig. 17, wherein the shearing rolls 78 and 79 are mounted upon shafts 80v and l831, which are journalled and driven, as has een d with registering lipswhich shear the strip at the dotted lines (Fig. 3), these rolls being properly timed for this urpose.

Between the several rolls is a tab e 82, as

lshown in Figs. 1, 3, 17 and the like, wliicli carries the' strip between sets of rolls. After assing the cutting oi rolls, as shown in ig. 1 .the severed strips pass down chute 83 While l have shown and described but a single embodiment of this `invention, it is to be' understood that it is capable of many` modifications. Changes, therefore, in the construction and arrangement may be made previously described. These rolls are' which do not depart fromthe spirit and sco slof the appended claims.`

1. A machine for iorming grooved'strips from atvmetal strips comprisinga pair of shearing rolls. for necking said strips at spaced intervals, means for bending the edges of the strips upwardly and inwardly 'between the necked in portions, means for upwardly and inwardly between the necked ln portions, and means for forcing said "strips through said machine.

.' 3. A machine for forming grooved strips from dat metal strips comprising a pair ot shearing rolls for necking a strip at spaced intervals, means `for bending the edges of the strip upwardly and inwardly between the necked in portions, means for shearing said strip at one end 'O said necked in portion, and means for orcingisad strip through said machine. Y

d. A machine for forming grooved strips from dat metal strips comprising a pair ci shearing rolls tor necking a strip at spaced intervals, a series of rolls in the path of i said strip for gradually creasing said strip longitudinally and torbending the edges upwardly and toward each other between; the necked in portions, and means for driving some ot said rolls to torce the strip through the machine.
